It’s Lady Veridiana’s 2000th birthday, and the pulsars have declared a Great Party — 666 days of non-stop demonic fun with DJ Lazarus. But humans, as always, plan to ruin it. While the demons dance, they aim to invade the castle, kill Veridiana, and end the Demon Curse.
As the newly appointed Black Architect, your job is to stop them. Use your budget to upgrade the castle and build deadly traps — but don’t harm the guests, or you’ll risk unleashing Veridiana’s legendary wrath! A tower defense deck-builder where strategy and adaptability are key.
Architect a labyrinthic castle worthy of a Lady Demon.
In Party Demon, players face waves of Humans looking to sabotage a Demon Party. Add rooms to the castle and build your path to the party for better odds. Also, adding unique rooms to the path can grant passives and effects depending on the room!
Build a diverse collection of cards and create unique decks!
In each run, players will be able to create a unique card collection. This way, it's possible to craft different decks for each situation, facing each wave with a new combination of cards!
Craft builds and use different trap combinations to get rid of pesky Humans!
Cards can work together and create different synergies. There are three types of Trap Cards, and for each, only one can be placed in a Room at once. Combine them well and create the best combos for slaying Humans!
Make sure the Demons get to the party unharmed and that the Lady Demon is Happy!
Humans aren't the only ones attending the Demon Party! Demons are also going through the same path, and they are VIP guests! They better arrive at the party unscathed. The Lady Demon won't like it otherwise!
